Ok so i was trying to find a good enough title for this because of the info that is given or the two ways one can look or take this video but the one thing that kept on sticking out was when you first hear about banking, you just can't help but go "guess you've never done that on a diamond" or "ever heard of Gandy or Gabriels?" But then he follows it up and you're like Oooh. Anyway apart from being funny at first (was thinking about posting it in the pics and gifs with a funny quote) i discovered that there may be something to be learnt from this and wanted to share it in general.
So take what you want from it
